THE DETECTION OF SHIGA TOXIN-PRODUCING Escherichia coli (STEC) O157 IN MEAT: A SYSTEMATIC REVIEW 肉类中产志贺毒素大肠杆菌(STEC) O157的检测:系统综述

Shiga toxin-producing Escherichia coli (STEC) bacteria, including the Escherichia coli O157, are described as pathogens producing toxin-like Stx 1 and Stx 2. These toxins become a significant virulence factor with a vital role in the outbreak of foodborne diseases worldwide. This study therefore aims to compile articles on STEC in several countries, using systematic review methods. Method : An online database on PubMed was accessed on 29 th October, 2020, to carry out the review, using STEC, E. coli O157, PCR, Stx 1, and Stx 2 as the keywords. This review utilized only full articles, written in English, and published within the past five years. Results : According to the results, there are nine related articles on this topic. In addition, primary E. coli O157 was found to produce toxins and greatly influence the pathogen's meat detection. All STEC strains were positive for Stx 1 , while PCR detected Stx2, and the whole-genome sequencing (WGS) provided forensic-level microbiological cross-contamination links from raw to ready-to-eat meat. Also, most of the articles showed cross-contamination occurred due to E . coli O157 bacteria's movement from the gastrointestinal tract to carcasses, and hygiene, as well as sanitation levels are the biggest causes of this contamination. Conclusion : E . coli O157 was identified not only on food like meat and spinach but also on non-food, including the environment. Improving hygiene and sanitation is a possible way to reduce the contamination of E . coli O157 on meat.
产志贺毒素的大肠杆菌(STEC)细菌,包括大肠杆菌O157,被描述为产生类似毒素的stx1和stx2的病原体。这些毒素成为一个重要的毒力因素,在世界范围内食源性疾病的暴发中起着至关重要的作用。因此,本研究的目的是利用系统综述的方法汇编几个国家关于产志贺毒素大肠杆菌的文章。方法:于2020年10月29日进入PubMed在线数据库,以STEC、E. coli O157、PCR、stx1和stx2为关键词进行综述。本综述仅使用了过去五年内发表的英文全文。结果:根据结果,有九篇相关的文章。此外,发现原代大肠杆菌O157产生毒素,并极大地影响了病原体的肉类检测。所有产大肠杆菌菌株均呈stx1阳性,而PCR检测到Stx2,全基因组测序(WGS)提供了从生肉到即食肉的法医级微生物交叉污染联系。此外,大多数文章显示交叉污染是由于E。大肠杆菌O157细菌从胃肠道转移到尸体,以及卫生和卫生水平是这种污染的最大原因。结论:E。大肠杆菌O157不仅在肉类和菠菜等食物中被发现,而且在包括环境在内的非食物中也被发现。改善个人卫生和环境卫生是减少大肠杆菌污染的可能途径。肉上的大肠杆菌O157。

We address the problem of detecting areas with markedly high values (hotspots) in spatial lattice data. Spatial lattice data are observations that include several spatial areas supplemented by neighboring information. The spatial scan statistics is an effective tool for hotspot detection. Echelon analysis is an analytical method to investigate the phase-structure of spatial data both systematically and objectively. In this paper, we describe the structure of spatial lattice data using echelon analysis and detect hotspots based on the echelon structure. As an application, we apply this method to simulation data of leachate accidents in final-disposal sites and detect considerably high-density pollution areas.
我们解决了在空间点阵数据中检测具有显著高值(热点)区域的问题。空间点阵数据是包括由相邻信息补充的若干空间区域的观测值。空间扫描统计信息是热点检测的有效工具。梯队分析是一种系统、客观地研究空间数据相结构的分析方法。本文利用梯队分析来描述空间点阵数据的结构,并基于梯队结构检测热点。作为一种应用,我们将该方法应用于最终处置场地的渗滤液事故模拟数据,并检测出相当高密度的污染区域。

Batch studies on anaerobic digestion were performed in 100ml bench top digesters (serum bottles) with solid wastes (limed fleshing) generated from tannery and primary sludge from effluent treatment plant of tannery liquid waste. Digestion was carried out under mesophilic condition. Batch reactors were run at two different organic loading rates. Gas production was higher in test reactor 1 (volatile solids load of 51.9 g/l) than test reactor 2 (volatile solids load of 15.8 g/l). VFA concentration in test reactors 1 and 2 had reduced by 11,970 mg/l (43%) and 2115 mg/l (28.4%) respectively. As biodegradability fraction present in the tannery solid wastes was lower, lag time for the onset of maximum gas production was longer. Based on experimental observation it is concluded that it is more appropriate to evaluate biomethanation potential of solid wastes in terms of biodegradable fraction of volatile solids present in the wastes.
在100ml台式沼气池(血清瓶)中对制革厂产生的固体废物(石灰肉)和制革厂废液废水处理厂的初级污泥进行厌氧消化的批量研究。在中温条件下进行消化。间歇式反应器在两种不同的有机负载速率下运行。试验反应器1(挥发性固体负荷为51.9 g/l)的产气量高于试验反应器2(挥发性固体负荷为15.8 g/l)。试验反应器1和2的VFA浓度分别降低了11,970 mg/l(43%)和2115 mg/l(28.4%)。由于制革固体废物中生物降解率较低,最大产气开始的滞后时间较长。通过实验观察,认为以挥发性固体的可生物降解组分来评价固体废物的生物甲烷化潜力更为合适。

had the surface soil removed and replaced by sandy soil . The cattle manure compost was used to improve soil fertility. The objectives of this study were to determine the effects of cattle manure compost application at rates of 0 (control), 10, 20 and 40 t ha - 1 on rice yields and on 137 Cs transfer to stems, leaves and panicles of rice in 2015. Results showed that rice yields were increased with rates of cattle manure compost. Application of cattle manure compost caused the increase of exchangeable potassium (K) in the soil, resulting in reduction of 137 Cs in rice parts. The 137 Cs concentration was higher in stems than in leaves and was not detected in panicles . The 137 Cs concentration in the aboveground parts of rice was decreased to the lowest (TF = 0 . 009) in soil that received 20 t ha - 1 of cattle manure compost, which was 2 . 4 times lower than that in the control . The transfer factor of 137 Cs (TF) in aboveground parts of rice was negatively correlated with exchangeable K in the soil . The ratio of 137 Cs / K was higher in stems than in leaves and that was related to the concentration of exchangeable Ca, and Mg in the soil . The results indicated that exchangeable K, Ca and Mg derived from cattle manure compost affected the uptake and distribution of 137 Cs in rice plants .

VISUALIZATION OF MULTIVARIATE DATA USING EXPANDED CONSTELLATION AND EXPANDED KANJI GRAPHS AND THEIR APPLICATION TO CLUSTERING 扩展星座图和扩展汉字图的多变量数据可视化及其在聚类中的应用

In this study, expanded constellation and expanded kanji graphs are proposed and the effectiveness of these graphs in the multivariate analysis is examined. To draw the expanded constellation graph, the variables are first placed on the circumference of the semicircle using factor loadings. Then, a line is drawn inside the semicircle by connecting the vectors of each variable. The constellation graph can simultaneously grasp both the tendencies of the objects and 𝑝 -dimensional variables. In the expanded kanji graph, the height and width of the kanji are determined using the mean values of the variables for each cluster. The kanjis are placed around the radar chart drawn using the standard deviation. The kanji graph can intuitively grasp the characteristics of each group in the cluster analysis. Herein, the effectiveness of the proposed methods is verified by evaluating the flavor of whiskey. The proposed methods show that whiskey flavors can be classified into five clusters: (1) “full-body and winey type,” (2) “sweet and balanced type,” (3) “smoky and balanced type,” (4) “full-body and smoky type,” and (5) “light-body and sweet floral type.”
本文提出了扩展星座图和扩展汉字图,并检验了这些图在多变量分析中的有效性。为了绘制扩展的星座图,首先使用因子加载将变量放置在半圆的圆周上。然后,通过连接每个变量的向量在半圆内画一条线。星座图可以同时掌握物体的趋势和𝑝维变量。在扩展的汉字图中,汉字的高度和宽度是使用每个簇的变量的平均值来确定的。汉字被放置在使用标准偏差绘制的雷达图周围。在聚类分析中,汉字图可以直观地把握每一组的特征。通过对威士忌的风味进行评价,验证了所提方法的有效性。所提出的方法表明,威士忌口味可以分为五类:(1)“酒香浓郁型”,(2)“甜味和平衡型”,(3)“烟熏型和平衡型”,(4)“酒香浓郁型”,(5)“轻体甜味和花香型”。
